The new edition of this book presents the basic principles of classical and matrix structural analysis. It provides a smooth transition from the classical approaches that are based on physical behaviour of structures in terms of their deflected shapes to a formal treatment of a general class of structures by means of matrix formulation in order to understand how the structural problems can be formulated in order to make them suitable for computer programming.
